定义于头文件 `<initializer_list>`
template < class E > const E * end ( std:: initializer_list < E > il ) noexcept ;		(C++11 起) (C++14 起为 constexpr)

针对 initializer_list 的 std::end 重载版本会返回指向 il 末尾元素后一位置的指针。

目录

参数

il - 一个 initializer_list

返回值

il. end ( )

示例

运行此代码

#include <cassert>
#include <initializer_list>
#include <iterator>
#include <numeric>
int main()
{
    std::initializer_list e = {2, 7, 1, 8, 2, 8, 1};
    assert(std::accumulate(std::begin(e), std::end(e), 13) == 42);
}
